Which is equal to one microvolt?

In the metric system, prefixes are used to denote powers of ten. The prefix 'micro' designates a factor of one one-millionth (10^-6). Therefore, one microvolt is equal to exactly one one-millionth of a volt. In amateur radio, receivers routinely deal with extremely weak incoming signals that are measured in microvolts. Understanding these small-scale prefixes is crucial for reading equipment specifications and grasping how sensitive modern radios truly are. It is easy to mix up similar-sounding prefixes. 'Milli' means one one-thousandth, and 'mega' means one million. Remember that 'micro' always refers to the millionth fraction of a base unit.
